JAMFS ALLINGHAM, OF CHICAGO, ILLINOIS.

To all whom it may concern:

w itknown that I. Janus AmaNonAM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Valve Mechanism for Lavatory i-\ppamtus, of which the following is a speeifiniiion. i V

This invention relates to improvements in means for operating valves, and has especial relation to valve mechanism for that type of bath-tubs, \vashdcisins and analogous ves-' sels wherein the valve or stopper controlling the waste or outlet opening is operated externally of and usually from beneath the. vessel by means of mnnections with a knob mounted on or near the rim of the tub or basin, or frame surrie-Jnding the same.

The objects of the invention are to provide a lavatory valve mechanism of such construction as to leave the interior of the vessel unobstructed. to be sanitary and cleanly, simple. drrzcble. etlicient in operation. and which will not readily get outof working order, and the parts of which can be easily put. in place and taken apart.

Another object of the invention is to pro vide a valve mechanism of such construction that the valve and its operative connections ma y maintain theinselvcs in any position to which they may be placed. thus avoiding the necessity of holding onto the knob to hold the valve open while discharging the contents ef the vessel.

Nnn'ierous other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art. to whichmyinvention pertains, to make and use the same. I will now proceed to describe it, referring to the accompanying drawings; in whie'h- Figure 1 is a view in side elevation of a valve mechanism embodying one form of the invention, showing it applied to a portion of a bath-tub: Fig. 2 is a detached. perspective view of the valve; Fig. 3 is a view partly in section and partly in elevation of a portion of the operatin -rod, showing means 'for adjustably connecting it to the valve 0 crating cmnk; Fig. 4 is a vertical sectiona view of the-valve mechanism shown in Fig. 1 and a part; of a bath-tub, illustrating thesame shortened for the convenieneefzof illustration, and by dotted lines the position to which the valve and operat- VALVE MECHANISM FOR LAVATORY APPARATUS.

Like. numerals of reference refer to corresponding parts throughout the difi'erent.

views of the drawings.

The reference numeral 15 designates a portion of a vessel, which in the present instance is shown as a part of a hath-tub, but which may be a wash-basin or similar vessel having in its bottom a waste opening 16 and in one of its walls near the top thereof an overflow opening 17, in the former of which ma v he fitted an externally screw-tln'eaded tube 18 to engage the internal screw-thremls at one end of an elbow 151, the other end of which is also preferably provided with internal screw threads to engage one. end of a pipe section 20, the other end of which pipe section is connected by means of asrrew-threaded collar 21 to an extension 22 on a T-jointor valve easing, which casing is designated as a whole by therefercnce nu meral 23, and consists of a hollow cdin drical casing Q-l having screw-threaded extensions 25 and 26 at its upper and lower ends, respectively, as well as the horizontally disposed extension 22,,which is connected to the pipe section 20 as before stated. \Yithin' the casing 24 is located another casing 27 between the walls of which, and preferably diametrically opposite each other, are formed by-passes 28 which communicate at their upper and lower ends with the hollow extensions 25 and 26, respectively, while the other portions of the inner casing 27 is in contact with or may form a part of the outer casing. The bottom of the inner casin 2? is provided with an opening or valve seat 29, and the top or transverse partition'of-said casing is provided with a central aperture and around" disk 3; of this valve is preferably prov with a vertical stem to pass through the opcniug 30 and stalling-box 31 thercaround, as is clearly shown in Fig. 4, to the end that the valve will be held so as to have a vertical movement, yet against lateral or webhling movement. The lower disk 33 of the valve is preferably downwardly beveled to lit in the correspondingly beveled opening 2!) of the inner casing 27, so as to produce a close joint and prevent leakage when the aim is seated.

As shown in Figs. 1, 4 and 7 of the drawings the'T-joint 23 is provided between its upper and lower ends with a hollow extension 36, the cavity of which communicates through an opening 37 (see Figs. 5 and 6) with the interior of the inner casing, and has on one of its sides a horizontally extending apertmed boss o8 or extension. Journalcd in the extension or boss 38 is a shaft :39 which has lixed on its inner portion a trigger or lever 40 which projects into the llilnr-casliig 27 and bet ween the disks 32 and Il of the valve, so as to engage the former did; and to raise the valve from its seat \\'llcll 'dcsircd. lligidly secured on the outer end of the shaft 3!) is a crank 41 which has at it other end a screw 42 or other suitable dzwire. which l extended through a slot 43 near onc end of a rod 44 and loosely connccts said rod-to the crank. The outer porlion of the rod 4-1 is extended through a lmrizmttall). disposed sleeve 45, which is connected to a vertically disposed sleeve 46 adju tably mounted on the operating-rod -tT. which sleeves constitute an adjustable coupling designated as a whole by the refercncc numeral -18 for said rods. Each of the sl eves 45 and 46 is provided with a set-screw -19 to hold their respective rods in the dcsired-position therein. As shown, the operating-nu] 47 is extended vertically through a- .-|-iitablc. su port 50' which support, in Figs. 1' and 8, is shown as being a bracket connected to the upper portion of the hath-tub or vessel. and in Fig. 4 as a se a rate support; therefrom, but it. will be on orstoodthat said support may be a part ofthe bathtub or vessel, or the slab or frame of a wash-basin, or any suitable support. Fitted around theupper portion of the op crating-rod 47 is a screw-threaded sleeve 51 referably con-- which is extended through an opening in the support 50 and has on its upper portion an hpertured head 52 provided with a hollow and internally screw-threaded extension 53 which communicates with the opening of the head 52, as will he clearly understood by reference to Figs. 1 and 4 of the drawings. Located in the hollow extension '53 is a plunger M which has at its outer end a s rin 55 to press it against the rod '57 which, it will he understood, is loosely extended through the sleeve 51 and head 59 hereon. Located in the outer portion of the extension 53 and against the outer portion of the spring 55 is an adjusting screw 56, which screw, spring and plunger constitute a frictional brake for the o crating-rod 47 so as to hold it, if desire in an; position to which it may be placed. Connected to the outer surface of the up Mr portion of the bath-tub 15 or vessel and surrounding the overflow opening 17 therein is an elbow 57, which has screwed to its lower end the upper end of a pipe section 58, the lower end of which is connected by means of a collar 59 or otherwise to the u per extension 25 of the T-joint. lonnected )y means of tension 26 of the T-joint- 23 is a pipe section 61 which may lead to a proper point for discharge.

Referring now to Figs. 1 and 4 of the drawings it will be seen that the upper end of the operating-rod 47 is provided with a knob-like handle (,9 by means of which the. operating-rml 47 may he raised and lowered so as to actuate thevalvc within the T-joint or valve casing. Fitted around the valvestcni 35 and engaging the extension or stuffing-hox 31 is a gland 35" which will retain the packing 31 in the stalling-box as is apparent. 'lo firmly secure the head 52 and sleeve 51 in place on the support. 50 a nut 63 may be screwed on the sleeve 51 on the oppthlit side of the support 50 from that on which the head 52 is located.

In Fig. 8 of the drawings 1 have shown a modification in the construction of the means for moving the operating-rod, and through its instrumentality of actuating the valve in the T-joint, which consists in providing the upper portion of the sleeve 51 with an enlarged hollow head or casing 52' instead of the head 52 as in the other construction just above described. In this modified construction the hollow head or casin 55.. is preferably cylindrical in shape, an has in its upper portion a vertical opening tit with whirh a hollow internal screw threaded extension 53, as in the other construction, comumnicates. Located in the extension 5. of this inmlitication is a plunger a spring and a regulating screw 56, as before described. Rotatahly mounted in the head 5"." is a handle for raising and lowera collar 60, or otherwise, to the lower exing the ojwrating-rod 47, and which con-- sisis of a cylinder 15 having on its inner surface diametrically tltfilfJst'tl cams (Hi and 61' (see Figs. 9 and 10) to cooperate with a pin (is transverselysecured in the upper end of the operating-rod 41'. which pin projects on one or both sides of said rod sutliciently to engage the surfaces of the cams (it; and (i7, so-that when the c 'linder 5 is rotated the pin (3S will be caused to travel upwardly on the surfaces of the cams (36 until it reaches the top thereof where it may rest and be retained by means of suitablerecesses 9 until, by a further rotation of the cvlinder 65 it will be displaced therefrom and will descend on the surfaces of the cam 37 until the bottom thereof is reached, when by a further rotation of the cylinder the same operation 6? is provided with a stem TOon. its upper portion which is extended through the openmg 64 in' the head 52. and may have thereon a handle 62- for turning the cylinder.

In Fig. 11 of the drawings I haveshown a modification in the construction of the cam cylinder, which consists in forming it of two hollow pieces 71 and 72 which are united together at up )osite. points by means of vertical straps 43 secured thereto. In this construction the upper member 75. of the cylinder has a stem to which a handle may be secured. as in the other construction.

From the foregoing and by reference to the drawings it will be seen and clearly understood that while I have shown the T- joint formed with a boss or enlargcun-nt on each side thereof. each of which has a bypass therein, and with the stutling-hox for the valve-stem. yet I do not desire. to limit myself thereto as the details of construction may be varied and some of the part-4 omitted without departing from the spirit of the invention. It is also obvious that instead of making the valve of two spaced apart disks as shown and described it may be otherwise formed. yetin such a manner that the trigger or lever 40 may engage the same.

The operation of the device is simple and as follows: 'hen the constructions shown in Fig-. l to T. inclusive. of the drawings is employed. the tension of the-spring 53 which presse the brake or plunger it against the qwrating-rml 47 may be regulated by means of the screw 56 located in the extension 53 so'that the pressure of the brake 5-1 will hold. the rod 47 in any position to which itsmay be placed. if desired. or the tension may be decreased to such an extent as to permit the rod 47 to be moved without impediment or through the members 18, 19, 20, Qiand tll 70 to the sewer or other point of discharge. In this operation it i obvious that by reason of the loose jointed connections above refcurcd to the operating-rod will have a rectilinear movement only, and that when the valve is 75 rai ed it will he held in such position, by reason of the action of the brake 54 which will also hold the operating-rod and valve at any intermediate points between the uppermost and lowermost positions thereof. As 30 the top of the inner casing 27 of the T-joint or valve-casing is closed, it is manifest that there will be no communication between the pipe sections and 58, but the by-passes will afford means for the outlet of water 35 from the overflow opening 17 when the valve is closed or seated.

When the construction shown in Figs. 8 to 11. inclusive, is employed virtually the same operation as above-described pet-to. ad, except that the rod -17 is raised and lowered by a rotary movement of the handle 62", in which operation the cams (i6 and (37 co-acting with the transverse pin 68 on the upper portion of the operating, lever will cause it to move vertically in a rectilinear line as in the other construction. The movement of the cam-handle or cylinder (35 may be regulated by means of the brake M. which in this modified construction is pressed against the 1 stem 70 by means of the spring 55, the tension of which is ,governed by the screw 56 as before stated.

By using the cam-handle constructed as shown in Figs. 8 to 11, inclusive, it is apparout that the operating-rod will be reeipro cated or raised and lowered by the rotary movement of the cam-handle. which movement may be in either direction. the cams being so arranged as to ali'ord a continuous contacting surface forthe transverse pin so that there will be no fulcrum or stop whereby the parts might be'strained when turned by the uninitiated.

From the above description it is obvious 1 5 that the device is susceptible of considerable nuiditication. besides those almve-referred to, without material departure from the prineiples and spirit of theinvention, and for this reason I do not desire to be understood as limiting myself to the precise form and arrangement of the several parts of the apparatus herein set forth in carrying out my invention in practice.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is- Y 1. The combination with a vessel having a waste'opcning in its bottom and an overttow opening in its upper portion, of a T'-.130'
